19.1.4 Building isotherms
19.1.4.1 About the Condensation alarm
To detect areas with potential moisture problems, you can use the Condensation alarm .
You can set the relative humidity above which the isotherm will colorize the image.
19.1.4.2 About the Insulation alarm
The Insulation alarm can detect areas where there may be an insulation deficiency in the
building. It will trigger when the insulation level (which is called the thermal index in the
camera) falls below a preset value of the energy leakage through a wall.
Different building codes recommend different values for the insulation level, but typical
values are 60–80% for new buildings. Refer to your national building code for
recommendations.
